The ends of the two pieces are joined together to form a box shape. As shown in FIG. 8, a recess 3 is formed at the open end of the switch cover main body 1, and a magnet 4 is adhesively fixed inside the recess 3.

着剤の接着力が低下して、磁石がスイッチカバー本体か
ら脱落するという問題がある。However, in both of the above conventional technologies, the magnet or iron plate is bonded to the concave part of the plastic resin flat plate using an adhesive, so the adhesive force of the adhesive decreases due to poor workmanship or deterioration over time, causing the magnet to switch. There is a problem that the cover falls off from the main body.
また、スイッチカバー本体はプラスチック樹脂平板を接
着剤で互いに接合しただけのものであるため、スイッチ
カバー本体を誤って床に落すと破損し易く、衝撃に非常
に弱いという問題もある。Further, since the switch cover main body is simply made of plastic resin flat plates bonded together with adhesive, there is also the problem that it is easily damaged if the switch cover main body is accidentally dropped on the floor, and is extremely susceptible to impact.
本発明の目的は、磁石の脱落を防止するとともに、強度
的にも優れた鉄板製操作盤用スイッチカバーを提供する
ことである。An object of the present invention is to provide a switch cover for an operation panel made of iron plate that prevents magnets from falling off and has excellent strength.
上記目的を達成するために、本発明は、スイッチカバー

、前記磁石を吸着面と垂直方向に移動自在としたことを
特徴とする。In order to achieve the above object, the present invention provides a switch cover in which a magnet is fixed to a switch cover main body, and the switch cover main body is attracted to an iron plate operation panel by the attraction force of the magnet. A vertical elongated hole is formed in the magnet, and a coupling member is inserted through the elongated hole to couple the magnet to the switch cover main body, so that the magnet is movable in a direction perpendicular to the attraction surface. It is characterized by

材が設けられた構成となっている。Further, the switch cover main body has a structure in which acrylic resin flat plates are fixed to both end surfaces of an acrylic resin member having a U-shaped cross section, and a triangular prism-shaped acrylic resin reinforcing member is provided at the inner limit of the fixed part. There is.

易となる。According to the above configuration, since the magnet is coupled to the switch cover main body by the coupling member, there is no fear that the magnet will fall off due to aging deterioration as is the case with adhesive bonding, and it is possible to prevent the magnet from falling off over a long period of time. In addition, the magnet has a long hole perpendicular to the attraction surface, and the coupling member is inserted through this long hole, so the magnet can move freely within the range of the long hole in the direction perpendicular to the attraction surface. When attaching the switch cover body to the surface of an operation panel, etc., a suction sound can be heard, making it easy to confirm suction.
また、スイッチカバー本体はアクリル樹脂で構成され、
しかも接合部がアクリル樹脂製の補強部材で補強されて
いるので、衝撃に対する強度が大きくなり、スイッチカ
バー本体を床等に落下させても破損する恐れは非常に小
さい。In addition, the switch cover body is made of acrylic resin.
Moreover, since the joints are reinforced with reinforcing members made of acrylic resin, the strength against impact is increased, and there is very little risk of damage even if the switch cover body is dropped on the floor or the like.
以下に本発明の一実施例を図面に従って説明する。 An embodiment of the present invention will be described below with reference to the drawings.
